EBASER-HOLDER FOR PENCILS.

Specification of Letters Patent.

Patented Aug. 14, 1917.

Application filed February 28, 1917. Serial No. 151,417.

To all whom it may concern: I 'Be it known that I, J ACOB A. Boos, a citizen of the United States, and a resident of Mount Vernon, in the county of Westchester and State of New York, have invented a new and Improved Eraser-Holder for Penoils, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved eraser holder for pencils and similar articles and arranged to provide an eraser of suflicient length to ordinarily last until the pencil is used up,

and to permit of removing a portion of the holder whenever the free outer end of the eraser has become worn down to the holder with a view to keep a portion of the eraser extending beyond the outer end of the holder.

In order to produce the desired result use is made of a ferrule adapted to hold an eraser and adapted to be fastened at one end to a pencil or a similar article, the ferrule being weakened circumferentially at apoint between the ends to provide a detachable portion.

A practical embodiment. of theinvention is represented in the accompanylng drawings forming a part of this specification, in

h I l I v the latter posltion 1n the ferrule, as will which similar characters of reference in- .dicate corresponding parts in all the views. Figure 1 is an enlarged elevation of one side of the eraser holder as applied to the butt end of a lead pencil;

Fig. 2 is a similar view of the other side of the same; I

Fig. 3 is a perspective view of the same with the outer portion of the holder partly detached; V i

Fig. 4 is an enlarged longitudinal central section of the eraser .holder as applied; and Fig. 5 is a cross section of the same on the line 55-0f Fig. 4.

The ferrule 10 is adapted to hold an eraser 11 preferably of rubber, and one end 12 of the ferrule 10 is fastened onto the butt of a lead pencil 13 or a similar 311310 18 1n the iisual manner, preferably, by providing the end 12 withindentations 14 embedded in the pencil material, as plainly ind cated in Fig. 4. The ferrule is provided intermediate its ends with a corrugated portipn 15 having the corrugations extending circumferentially, and fitting the corresponding portion of the eraser 11 to securely hold be readily understood by reference to Fig. 4. The bottoms of the outermost and innermost corrugations are weakened, preferably by perforations or by spaced slits, indentations or the like, as indicated by 16 and 17. The outer portion 18 of the ferrule extending from the weakening 16 to the outer edge of the ferrule is provided with two parallel weakenings 20 and 21 spaced a short distance apart and extending lengthwise of the ferrule from the outer edge of the ferrule to the weakening 16 at which line the slit extends from the weakening 20 to the weakening 21, as plainly indicated in Fig. 1.- By this arrangement the portion between the said weakenings 20, 21 forms a narrow band 22 which can be readily torn ofl by the user (see Fig. 3) to allow of subsequently peeling or tearing off the remaining portion 18 along the weakening 16. It willvbe noticed that the eraser 11 extends beyond the outer end of the ferrule when the pencil is new and when the projected portion ing a narrow band 25 adapted to be peeled off lengthwise of the ferrule and preferably located diametrically opposite the band 22 formed by the weakening lines 20 and 21 above referred to. Thus if the projecting portion of the eraser 11 has been worn down to the upper edge of the corrugated portion 15 then the operator removes the band 25 intermediate the weakenings 23 and 24 to then remove the portion 15 to unobstructedly disclose another portion of the eraser for erasing purposes. The pairs of weakening lines 20, 21 and 23, 24 are preferably made on opposite sides. of the ferrule so as not to unduly weaken the general construction of the ferrule. It will be noticed that the corrugations '15 aid in holding the eraser 11 in place in the ferrule and the weakening lines 16 and 17 are made at the bottoms of the corrugations so as to. present no undesirable raw edges after the portions 18 and 15 are. removed as above described.

The ferrule shown and described is very manufactured and applied tolead pencils and similar articles to provide sufficient eraser material for erasing purposes to last until the pencil 13 1s used up.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. An eraser holder, comprising a single piece ferrule adapted to hold an eraser and having an outer smooth portion, an intermediate corrugated portion and an inner portions, the outer and intermediate portions having integral bands eXtendin lengthwise of the ferrule and adapted to e peeled off preparatory to peeling off the remainder of I the corresponding outer and middle portions. I

3; An eraser holder, comprising a singlepiece ferrule adapted to hold an eraser and having an outer smooth portion, an intermediate portion and an inner portion, the intermediate portion being weakened circumf erentially adj acent'the outer and inner portions, the outer and intermediate portions having each two parallel weakened lines extending lengthwise of the ferrule and forming detachable integral bands adapted to be peeled off prior to peeling off the remainder of the corresponding outer and intermediate portions. 4. An eraser holder, comprising a ferrule adapted to hold an eraser and adapted to be fastened at one end to the butt end of a pencil or similar article, the ferrule having circumferential corrugations spaced from the ends of the ferrule,'the bottoms of the first and last corrugations being weakened to provide detachable portions, and weakenings extending lengthwise of the ferrule, one reachingfrom the outer end of the ferrule to the first circumferential weakening and the other extending fromone bottom corrugation to the other and on the side of the ferrule opposite the one on which the first lengthwise weakening is located.

5. An eraser holder, comprising a ferrule adapted to hold an eraser and adapted to be fastened at one end to the butt end of a pencil or similar article, the ferrule having circumferential corrugationsspaced from the ends of the ferrule, the bottoms of the first and last corrugations being weakened to provide detachable portions, and weakenings extending lengthwise of the ferrule, one reaching from the outer end of the ferrule to the first circumferential weakening and the other extending from one bottom corrugation to the other and on the side of the ferrule opposite the one on which the first lengthwise weakening is located, each of the-said lengthwise weakenings having two parallel portions.
